ことを特徴とする拡巾掘削工法。 In the soil cement underground pile method, a hydraulic swivel joint is installed outside the excavation rod, and a hydraulic cylinder is installed inside the swivel joint and connected to the swivel joint to rotate the excavation rod while moving the piston rod up and down using hydraulic pressure. By adjusting the widening bit through the upper 3
By excavating the bottom of the pile or the bottom of the wall to an extent larger than the standard soil pile or continuous wall excavation dimensions completed with wing bits, the base area becomes much larger and the bearing capacity increases, making it possible to perform wide excavation. This widening excavation method is characterized in that by returning the widening bit to its original position when stirring and mixing with milk is sufficiently completed, it is possible to ascend while stirring and mixing at the upper standard dimension and finish the construction.
